Applicator tubes have your weight versus plunger "notches" right on the plunger. If you are strongly suspecting your a + hit, two doses 48 hours apart. Then every 2 weeks until forever, if you want. Same for PROPHYLAXIS PROTOCOL.

I have the MSD (formerly MSDS) and there are 3 "proprietary" compounds as vehicles. I've done the math and for any of these 3 compounds to be toxic to humans the amount of Ivermectin you would be taking would probably kill you 30X over because of the Ivermectin amount. Like buckets full.

It's a bloodstream recycling drug. It'll stay in you for a long time (like THC does) until it eventually leaks out. Why you wait 2 weeks between doses. The entire time you are full measure protected.
